Using tasks to measure consumers' ability to apply food guide recommendations: lessons learned

Area of Science:

• Nutrition Science
• Consumer Behavior Studies
• Dietary Guidance Evaluation

Background:

• Assessing the practical application of dietary guidelines is crucial for public health.
• The Northeast Regional Food Guide (NERFG) aims to promote healthy eating using local, seasonal foods.
• Existing methods for evaluating food guide usability require refinement.

Purpose of the Study:

• To evaluate the usability of the Northeast Regional Food Guide (NERFG) through consumer task performance.
• To identify lessons learned from using comparison and substitution tasks for assessing dietary message application.
• To determine the potential of these tasks for both practical decision-making and educational purposes.

Main Methods:

• Consumers engaged in comparison and substitution tasks designed to mirror real-life food choices.
• Task performance was analyzed to gauge the understandability and applicability of the NERFG.
• Qualitative and quantitative data were collected on user experience and task outcomes.

Main Results:

• The NERFG demonstrated utility in supporting consumers' daily dietary decisions.
• The implemented tasks showed promise in assessing the application of food guide messages.
• Identified limitations include the need for improved score differentiation between consumer groups.

Conclusions:

• The developed tasks are a valuable tool for assessing the usability of food guides like the NERFG.
• Future research should focus on enhancing task validity and reliability.
• These tasks hold potential for use in nutrition education programs to improve dietary habits.
